Lillian married Leo Wyatt before he joined the army as a medic during WWII. She had trouble getting over Leo after his death, until he visited her in her dreams and said his final goodbye.

When Piper went to visit her, Lillian said that Leo had the most amazing touch, like a healing touch. She told Piper that she was still thankful for Leo, because if he hadn't come to her to tell her everything was ok, she wouldn't have met her second husband.
With her second husband, she had two children, grandchildren and even great-grandchildren.
